摘要
通过放射免疫测定法对１～４月母乳及相应时期婴儿粪便中分泌型免疫球蛋白Ａ（ＳＩｇＡ）含量进行检测。结果：１～４月母乳及婴儿粪便中ＳＩｇＡ含量基本稳定，无显著变化。而母乳喂养儿粪便中ＳＩｇＡ含量显著高于同一时期的人工喂养儿。提示：在生后４个月内母乳能为婴儿提供大量ＳＩｇＡ，对维持尚未发育成熟的婴儿肠道的免疫功能具有重要意义。
bjective To determine the concentration of secretory immunoglobulin A (SIgA ) in human milk at 1,2, 3 and 4 months after delivery and in infants'feces in the same period and find out the effect of milk on the content of SIgA in infants's intestine.Methods 2 0 women and 1 2 breast feeding infants and 1 3 formula feeding infants were studied,and milk and infants's feces were collected at 1,2, 3 and 4 months after delivery,respectively,The con-centrations of SIgA in milk and feces were determined by radioimmunoassay. Resul ts No apparent changes in the concentration of SIgA were found in human milk and feces from breast feeding and formula feeding infants at 1～4 months after delivery, but the concentration of fecaI SIgA in breast feed ing infants was significantly higher than that in the formula feeding infants,during the first 4 months after birth. Conclusions Human milk can provide a large amount of SIgA for infants.We conclude from these data that human milk is benificial in protecting the immunological function of infants digestive tract.
